L'appariement des styles de motivation et l'évolution de la satisfaction conjugale.

Examined whether couples tend to adopt self-determined motivational styles and observed the relationship between couples, motivation style pairings and marital satisfaction. The sample consisted of 226 married or cohabiting couples participating on a voluntary basis. 87 couples completed the questionnaires a 2nd time 36 mo later. The instruments used were the Couple Motivation Questionnaire and the Dyadic Adjustment Scale. Results showed that there is a significant relationship between women's and men's motivations to live together. The most frequent couples' pattern of pairing was 2 people with self-determined motivational styles. Furthermore, this couple pattern was related to higher marital satisfaction.

Étude de la valorisation de la magnétite titanifère de la région de Magpie,Québec: Partie II — Composition et structure de la fonte et de la scorie obtenues par fusion réductrice d'un concentré magnétique

Abstract

A magnetic concentrate from Magpie titaniferous iron ore has been smelted in a pilot scale arc furnace. A pig iron containing most of the chromium and vanadium of the ore has been obtained, while the titanium remained in the slag. The main phases occurring in this slag are a pseudobrookite-type solid solution, a spinel and several silicates. The composition of pseudobrookite depends on the reducing conditions and can reach 90% TiO₂. The spinel composition is on the MgAl₂O₄ side of the MgAl₂O₄-Mg₂TiO₄ solid solution.

Résumé

Des essais de fusion réductrice au four électrique en présence de carbone, ont été réalisés sur un concentré magnétique du minerai de Magpie. Ce traitement permet d'obtenir une fonte contenant la plus grande partie du chrome et du vanadium, et une scorie titanifere. Cette dernière est constituée d'une pseudobrookite, d'un spinelle et de silicates. La pseudobrookite est une solution solide de composition variable suivant le degré de réduction et titrant plus de 90% en TiO₂. Le spinelle est de composition voisine de MgAl₂O₄.     

Review of Le mécanisme de la vision des couleurs.

Reviews "Le mecanisme de la vision des couleurs," by J. Segal (see record 1954-02115-000). Visual specialists for the most part still subscribe to the classical trichromatic conception with regard to the color mechanism, even though recent evidence concerning the nature of the retina and the involved neural functions seemingly has failed to narrow the gap that long has existed between fact and theory in vision. After many years of intensive study and experimentation, Segal presents in this work his own constructive formulation, along with the arguments that are associated with its development. Although the new theory is cast in the familiar trichromatic mold, he breaks sharply from conventional thinking in regard to the details of visual physiology. Divesting himself of prevailing conventions, he envisages the mechanism underlying color in terms of essentially new relationships. The logical reasoning on which the new prospect of the mechanics of color is based is worked out in considerable detail and in relation to much of the relevant knowledge that steadily has been accumulating. In a thoroughly scholarly manner, Segal has presented what amounts to a simplification of the physiological mechanics of color vision. Whether the new prospect is confirmed in its entirety, or in part only, he has made a contribution to the psychophysiology of color that is bound to serve as the basis for further critical studies designed to come more closely to grips with the true nature of the color mechanism.

Le r?le des interactions mère-enfant et de la dépression maternelle à l'age préscolaire dans la prédiction de l'attachement de l'enfant à l'age scolaire.

Examined the contribution of mother–child partnership and maternal depression during the preschool period to the prediction of the child's attachment classification at early school-age in 91 French-Canadian children. Mother–child interactions were observed during a collaborative task using a scale measuring synchronized and reciprocal social-affective exchanges in the mother-child partnership (age 3–5 yrs). Maternal depression was assessed during the same lab visit using the Beck Depression Inventory. At a second lab visit (age 5–7 yrs), attachment classifications were assigned on the basis of reunion behaviour. A discriminant function analysis showed that reciprocal mother–child partnerships in the absence of maternal depressive symptom predicted security of attachment two years later, whereas failed reciprocity in the presence of maternal depressive symptoms predicted both insecure disorganized and ambivalent attachment. Quality of prediction is high for secure, ambivalent and disorganized children, although ambivalent and disorganized children cannot be distinguished from each other. Results support the importance of mother–child interactions and maternal depression as preschool variables associated with security and insecurity of attachment at early school-age.

Les pratiques parentales des parents d'enfants en difficultés de comportement: Effets de la dyade parent-enfant.

The study set out to indentify the differences and the similarities in the parental practices of mothers and fathers of kindergarten children known to exhibit problem behaviour (n = 109) as it relates to parenting a son or a daughter. The results obtained from self-reported parental measurements and direct observation of the parent–child dyad in a play situation revealed a greater complicity in dyads of the same sex during the play situation and, in opposite sex dyads, a significant link between the expression of negative parental emotions during interactions and problem behaviour in children. In girls, negative interactions with both parents, particularly the hostile disciplinary practices used by the mother, seem to be associated with problem behaviour; in boys, the mother's feeling of inadequacy and the poor quality of the father's presence seem more closely linked with these difficulties.

Direction des effets entre le tempérament de l'enfant et la sensibilité maternelle.

This study aims to examine the potential direction of effects between infant temperament and maternal sensitivity between 15 and 18 months, while considering five different temperament dimensions (activity level, pleasure, social fearfulness, anger proneness and interest/persistence). More specifically, it aims to verify if the direction of effects and the strength of the relation between these two variables vary as a function of the level of psychosocial risk infants are exposed to and infant gender. Fifty low-risk and 98 high-risk mother-infant dyads (defined as a function of mother status: adult or adolescent) were evaluated twice during home visits. At 15 and 18 months, mothers completed a French-Canadian version of the Toddler Behaviour Assessment Questionnaire (TBAQ; Goldsmith, 1996), the Questionnaire d'évaluation du comportement de l'enfant (QéCE; Lemelin, Tarabulsy, Provost, Fournier, Robitaille, Hémond & Tessier, 2007), and observers completed the Maternal Behaviour Q-Sort (MBQS, Pederson & Moran, 1995). Results obtained in the study show that the strength of the relation, and the direction of effects, between infant temperament and maternal sensitivity vary as a function of the temperament dimension taken into account. In addition, the direction of effects also sometimes varies as a function of the level of psychosocial risk and infant gender. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

L'édition spéciale de la neurologie cognitive: Préface.

Discusses this special edition in cognitive neuroscience in the Canadian Journal of Experimental Psychology (CJEP). The editors decided to focus their efforts on three "hot" research areas in Cognitive Neuroscience--perception and action, multisensory integration, memory and higher-order cognition--and within each domain highlighting how different research methodologies can be brought to bear on the issue of the neural bases of higher mental functions.

élaboration et validation d'un instrument de mesure de la conscience phonologique.

This study describes the steps in developing and validating a French-language instrument to measure phonological awareness. The selected task involves ranking from a list of 4 words presented orally. Ss must choose the word that begins differently than the others. To decrease the mnestic difficulty of the test, illustrations accompany the words. Two pre-experiments using a bank of 20 items led to preparation of a final version of the phonological awareness test, which consists of 10 items. The validity and reliability of this version were assessed using 57 pre-schoolers and 60 kindergartners. In terms of validity and reliability, the psychometric features of the test were deemed satisfactory for the kindergarten students but deficient for the pre-schoolers.

étude comparative de nourrissons prématurés et nés à terme et des modes de stimulations qu'ils expérimentent au cours des six premiers mois.

Compared preterm and fullterm infants' temperament and development and to evaluate the physical and social stimulations they experience at 2, 4 and 6 months (correcting for prematurity). Fifty-six mother–infant dyads, including 28 premature and 28 fullterm infants, participated in the study. The groups did not differ on temperament and developmental measures, neither on physical environment (density, toys, accessories). However, significant differences were found regarding social stimulation. Mothers of preterm infants had less optimal sensibility-contingency scores and used more distal stimulation at 2 months than mothers of fullterm infants. During the first 6 months, premature infants spent more time in activities involving the immediate family, whereas fullterm infants went more frequently on outings. At home, fullterm infants interacted more with people from their social network. These stimulations could eventually have an impact on infant development.

L’importance de la famille: Psychologie de la famille et famille de la psychologie.

Research on the family lies at the interface between basic and applied science. After tracing the scientific and practise roots of research on the family, I highlight that research to date has neglected the perspective of fathers. I propose that as in regular families, the family of Canadian psychology is diverse and constantly evolving. Key findings in psychology of the family include the importance of multiple perspectives, the benefits of quality time, and the toxic effects of conflict. These concepts apply equally to the family of Canadian psychology. I suggest that through involvement in the Canadian Psychological Association, psychologists can be enriched by multiple perspectives, can benefit from communication with one another to work together to advance psychology for all.

La perception de la relation père-enfant et l'adaptation des enfants suite au dévoilement d'une agression sexuelle.

The present study explores the link between the father–child relationship and outcomes following child sexual abuse disclosure cases. Seventy-nine children completed measures evaluating perceived attachment security to mother and father (Kerns Security Scale; Kerns, Klepac, & Cole, 1996), as well as the child's internalised and externalised behaviour problems (Dominic Interactif; Valla, Bergeron, St-Georges, & Berthiaume, 2000), and self-esteem (Self-Perception Profile for Children; Harter, 1985) after the disclosure of the sexual abuse. Results indicated that perceived attachment security to the father figure is not correlated with perceived attachment security to the mother. A series of hierarchical multiple regression revealed that perception of paternal attachment security added to the prediction of internalised and externalised (marginal) behaviours over and above perceived attachment security to the mother. Results are discussed in terms of implications for intervention with sexually abused children. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Les conversations mère-enfant et l'attachement des enfants à la période préscolaire.

This study examines whether mother-child conversation patterns are associated with child attachment classifications at preschool age (N=80). Results revealed that a child's discourse style is similar to that of her or his mother. In comparison with mothers of insecure ambivalent or disorganized children, mothers of secure children made more frequent verbal statements that elaborated emotional content. Mothers of avoidant children were more inclined to minimize emotional content than mothers of secure children. In comparison with other mothers, those with a disorganized child were sharing more frightening and hostile content, or made more verbal statements accompanied by aggressive behaviors. Secure children made more frequent verbal statements that elaborated emotional content than avoidant and disorganized children. Disorganized children made more controlling verbal statements as well as statements accompanied by aggressive or flight behaviors. Finally, our results showed that child capacity to elaborate emotional experiences partially mediated the link between maternal capacity to elaborate emotional content and child security of attachment. Our results emphasize the importance of mother-child conversational exchanges for the development of attachment in preschool children.

Impact psychologique de l'horaire de travail et de la participation aux taches familiales chez des couples à double carrière.

The present research examined the joint impact of characteristics of the work schedule and the participation in household work on psychological distress and parental role strain as well as stress crossover. A total of 93 dual-earner couples with at least one child living at home participated. Multiple regression analyses revealed that predictive variables of the psychological distress or the parental role strain differed for men and women and that the parental role strain was related to the psychological distress for both men and women. Results partially support the hypothesis of stress crossover since no characteristics of work schedule of the husband's and wife's were related to parental role strain of the spouses, but women's participation in the children's care was associated with men's higher parental role strain. These results underline the importance of studying strains associated with specific social roles of women and men with respect to effects of both work schedule and family strains related to psychological distress.

Engagement et persuasion par la peur: Vers une communication engageante dans le domaine de la santé.

Evidence from psychological research has shown the importance of fear on attitude and/or behavior change. The experiment hereby quoted tests the influence of commitment (high vs. low) on an attempt of persuasive message for a forthcoming effect, that is, after reading an antialcohol message to subjects. The idea consists in inducing alcohol consumers toward modifying their attitude and behavioral intentions toward alcohol. As expected, the high committed drinkers (i.e., regular drinkers) resist persuasion (on the level of both attitude and intention). The low committed drinkers (i.e., occasional drinkers) do not resist persuasion but adopt further on a more favorable attitude toward alcohol. The drinkers who had read a strongly threatening, yet at the same time strongly reassuring, message express the strongest intention to reduce their alcohol consumption. Results are described with reference to Witte's (1998) extended parallel process model. A new perspective is presented at the end of our paper, that is, toward a "committing communication."

Valeurs de fréquence subjective et d'imagerie pour un échantillon de 1,916 substantifs de la langue fran?aise.

Reported norms of rated subjective frequency of use and imagery on 7-point scales for 1,916 French nouns in 454 17–29-yr-olds. Interjudge reliability was assessed by calculating the correlation between the mean ratings of items repeated in the booklet, between the mean ratings obtained from odd-numbered and even-numbered respondents, and by computing the Cronbach alpha statistic for each page of the booklet. Results indicate that although the estimates provided by female and male participants were highly correlated, the former gave a slightly higher frequency rating to the word sample but a slightly lower imagery rating than the latter did. Moreover, female respondents gave slightly more extreme ratings on the frequency and imagery scales. An analysis of the absolute difference between female and male ratings revealed a discrepancy of one half point or more on 20% of the word sample for frequency and 13% for imagery. On both scales, the mean absolute difference between male and female ratings was larger than that obtained by chance alone. The mean, standard deviation, and percentile rank of the frequency and imagery ratings for each item are appended together with their objective frequency of occurrence in Baudot's (1992) dictionary.

Review of Psychothérapie cognitive de la dépression, 3e édition.

Reviews the book, Psychothérapie cognitive de la dépression, 3e édition (Cognitive psychotherapy for depression, 3rd edition) by Ivy Marie Blackburn and Jean Cottraux (2008). This third edition of the first French-language book about cognitive psychotherapy for depression permits to immerse the work of professor Beck. This classical work aims to be an excellent introduction, for both mental health professionals who want to extend their horizons and beginner students in psychology and psychiatry who want to be trained in cognitive psychotherapy for depression.

Où en est la cognition sociale? Sociogenèse et sélection ontogénétique des pensées sociales.

Maintains that sociogenetic models of human development invoke processes such as intersubjectivity, experiential canalizaion and ontogenetic selection to explain both interindividual differences and personal changes in children's representations of social reality. Studies stressing information processing focus upon procedural aspects of social thought, whereas constructivists emphasize age graded shifts in conceptual abilities. In contrast, socioconstructivists analyze the bi-directional influence between specific interpersonal relations and the evolution of children's cognitive skills. The authors argue that a major theoretical challenge for this field of study involves linking children's sociocognitive capacities to social adaptation in everyday settings. Theoretical and methodological implications of the sociogenetic model for understanding inter-personal and intra-personal diversity in social thought are discussed.

L'attachment à l'age scolaire et le développement des troubles de comportement.

The purpose of this longitudinal study was to examine the association between the mother–child attachment relationship and behavioural problems among a test group of 120 Francophone Canadian children from mixed social and economic backgrounds. The Strange Situation protocol was used to measure attachment styles when the children were between the ages of 5 and 7 yrs. Each child's behavioural difficulties were assessed by his or her educator or teacher during 3 developmental periods: 3–5 yrs, 5–7 yrs, and 7–9 yrs. Results show that disorganized insecure attachment is associated with an increased risk of developing exteriorized and interiorized behavioural troubles between the ages of 5 and 7. The authors also observed exteriorized behavioural problems among children with anxious-ambivalent attachment, especially in the 3–5 age group. Avoidant children, usually assessed positively, received exteriorization scores during the 5–7 period which were significantly below those of securely attached children. Avoidant boys also exhibited more interiorized symptoms during this time-frame. Analyses of the persistence of behavioural problems also showed increased risk among disorganized and ambivalent children with secure or avoidant attachment styles.

Validation canadienne-fran?aise de l’échelle des styles d’orientation des buts (ESOB).

The Goal Orientation Scale (GOS) developed by VandeWalle, Cron and Slocum (2001) is used to assess learners’ goal orientation style. However, this scale is in English, limiting its applications with francophone populations. This study documents the psychometric properties of a French version of the GOS. The instrument was translated and verified by expert translators then administered to 219 French-speaking students enrolled in two Quebec Universities. The subjects also responded to a measure of fear of negative evaluation, general self efficacy and locus of control. Analyses of the factor structure, internal consistency, temporal stability and the pattern of correlations with external variables indicates that this French version converges with the original English instrument.
